Diplogastridae
Diplogastridae, formerly Diplogasteridae, are a family of nematodes (roundworms) known from a wide range of habitats, often in commensal or parasitic associations with insects. Description Diplogastrid nematodes are characterized by a distinct "two-lobed" pharynx (hence their name from the Greek διπλόος = "double" and γαστήρ = "stomach"), the second ( posterior) lobe being composed mostly of glandular tissue. Most known species also have at least one tooth, which has presumably allowed them to access many new food sources compared with the related nematodes of Rhabditidae (including ''Caenorhabditis elegans''), most species of which feed on bacteria. Several diplogastrid species also have a polyphenism in their mouthparts, allowing resource specialization within species. The wide array of feeding modes in the Diplogastridae is reflected by the relatively high diversity and complexity of their mouth structures, which show accelerated rates of evolution in comp ...

Pristionchus Pacificus
''Pristionchus pacificus'' is a species of free-living nematodes (roundworms) in the family Diplogastridae. The species has been established as a satellite model organism to ''Caenorhabditis elegans'', with which it shared a common ancestor 200–300 million years ago. The genome of ''P. pacificus'' has been fully sequenced, which in combination with other tools for genetic analysis make this species a tractable model in the laboratory, especially for studies of developmental biology. Mouth dimorphism Like other species of ''Pristionchus'' and many other free-living nematodes, ''P. pacificus'' exhibits a polyphenism in its mouthparts that allows individual nematodes to specialize on different food sources, which has made the species a case study in phenotypic plasticity. The polyphenism has two forms (morphs). The most common type, at least in wild-type lab strains, is the "eurystomatous" morph, which can feed on both bacteria and other nematode species. The "stenostomatous" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
